CT32 Thermostat—Resolving a Malfunction
Resolving Errors on a New Device:
If this error occurs on a newly installed device, it is usually an indication that the Z-Wave device is too far from the panel to maintain a signal.
Determine if a signal extender may be your best option. Most Z-Wave devices that plug into a power outlet can be used to relay a Z-Wave signal.
Resolving Errors on a Pre-Existing Device:
If the error occurs on a device that has been installed for a long time, it may be that the batteries are too low to maintain a signal.
Learn how to replace the batteries in the CT32 thermostat here: CT32—Battery Replacement.
You will also need to clear the error from the panel memory.
